VENEER-DRIER.

SPECIFICATION forming part of Letters Patent No. 717,255, dated December30, 1902.

Application filed October 24, 1901I Serial No. 79,785. (No model.)

To all whom it may concern:

Be it known that I, AARON S. NICHOLS, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful-Improvement in Veneer-Briers, of which thefollowing is a specification. I

This invention is an improvement in veneerdriers having their platenssuspended in Vertical position and opened and closed automatically bysuitable mechanism.

The invention relates mainly to the construction of the platen-supportsand will be f nlly understood by the accompanying drawings, in which Ishow, at

Figure l a front elevation of a veneer-drier embodying my invention, andat Fig. 2 a transverse vertical section of the same. Figs. 3, 4, and 5are enlarged detail views of parts of the apparatus.

In said drawings, 6 6 represent the platens of the drier, flexiblyjoined to supportingbars 7 7 and heated internally by steam admitted bythe pipes 8. The condensations are conducted awayby pipes 9. Thehangerbars are pivoted at their upper ends on pins 10, and these pinsrest on longitudinal supporting-beams 11 11, one at each side of thebars. The beams are supported at either end on corner-posts 12, and theposts at each end of the machine are tied together by bolts 13 and 14..The posts on each side are also united at the bottom bya bolt 15. Theplatens are adapted to receive the veneers 16 between them and areforced into close contact with them by toggles 17 at each end of theseries of platens. These toggles are extended and contracted by rods 18,operated by cranks 19 on the rock-shaft 20, which is operated atsuitable intervals by any suitable means. ,I have shown thesteam-cylinder 21, having a piston operating a crank 22 on the shaft, asa desirable form of motor for this purpose. The toggles when contracteddraw the end platens away from their neighbor platens, and in order thatthe other or intermediate platens may also open at the same time Iconnect each pair of adjacent platens together by a short link 23, eachreceiving a bolt at one end and havinga slot in its other end. The linksare secured to the platens by bolts 24, passing through theclose-fitting opening in one link and the slot of another link. Thelinks overlap each other, as seen at Fig. 3, and it is desirable thatone series of them be placed on the top of the platens and two otherseries below them. By means of the links the opening movements of theend platens are communicated to the middle ones, so that all openequally and at the same time and allow the moisture to escape from allthe veneers. -In these opening movements the platens swing on the pivots10; but it is not desirable that the pivots change positions at all, andin order that they may remain stationary in their proper relativepositions at all times I place over each of,the series of pivots 10 anotched spacing-bar 25 and bolt it down at its ends by bolts 26.- Thisbar should be rigid, and it may be made of channel-iron, as shown, sothat it will rest on both of the companion beams 11 and engage thepivots at both sides of the hangers 7, though the channel feature ofthe'bar is not necessary.

The platens are provided with bottom ledges 27, on whichthe veneers arepositioned, and

with end recesses 28 to give opportunity to take hold of the veneers.

1. The veneer-drier having vertical platens supported by pivotedhangers,beams on which the pivots of the hangers rest, and a notchedspacing-bar sitting over the pivots, substantiallyv as specified,

2.. The combination in a veneer-drier, of a series of vertically-hungplatens, mechanism 'for opening and closing the platens, plainsurfacedbeams supporting the pivots of the platen-hangers, and notched barssitting over and spacing said pivots,su bstantially as specified.

3. The combination in a veneer-drier, of a series of vertically-hungplatens, mechanism for opening and closing the platens, slotted linksconnecting adjacent platens and cansing the opening of all of them,beams supporting the pivots of the platen-hangers, and

means for holding said pivots stationary as to location, substantiallyas specified.

4. The combination in a veneer-drier, of a series of vertically-hungplatens, mechanism for opening and closing the platens, slotted linksconnecting adjacent platens and cansing the opening of all of them,beams sup porting the pivots ofthe platen-hangers, and means common toall the pivots for holding them stationary as to location.

5 5. The combination with the platens, the hangers and the pivots of thelatter, of the beams supporting the pivots, and stationary spacing-bars,each controlling all the hangerpivots on one side of the machine,substan- IO tially as specified.

6. The combination in a veneer-drier of a series of platens hung invertical positions upon bars pivoted stationarily at their upper ends,mechanism for opening the end platens, and slotted links connecting allthe adjacent platens together so that the opening of the end platenscauses the opening of the intermediate platens, substantially asspecified.
